David: I’m just trying to figure out why you would do this, why anyone would do this.
Shadow King: The reason anyone would do this if they could — which they can’t — would be because they could — which they can’t.
David: Is this the first part of some kind of magic trick?
Shadow King: I don’t do magic, David. I do superpowers. One takes being a mutant. The other takes dark eyeliner.

David: I’m not that guy anymore.
Shadow King-as-David: You’re wrong. Summerland may have dulled your killer instinct, but trust me, it’s still in you. It’s time to leave this place and reclaim your proper life.
David: No. Not without Syd and my friends.
Lenny: Ugh. Now who’s in a Lifetime movie?
Shadow King-as-David: Then I’ll be rid of you another way.

Shadow King-as-David: Hello, Syd.
Syd: Hello, Evil David.
Shadow King-as-David: What? How did you– ?
Syd: I know an evil doppelgänger when I see one.
Plus, your eyes are yellow.
Shadow King-as-David: Silence!
Syd: Are you here to kill David?
Shadow King-as-David: Oh, you non-evils are so naive. I’m here to save David from the smothering teat of his mutant buddy group.

Shadow King: They made Lame David too lame to leave Summerland. He’s got to attack that base.
Lenny: But how do we make him do that?
Shadow King: By turning the Mutants here against him so he’ll run screaming from this rancid cocoon into the welcoming arms of darkness.
